Micro resistance slowly-closing butterfly check valve, pneumatic valve - HH49X large diameter flange check pneumatic valve

the micro resistance slowly-closing butterfly check pneumatic valve main features: small volume, light weight, the structure length is only about a third of swing. , hydraulic slowly-closing system is good, is not affected by the medium inside the pipeline, pneumatic disc slowly-closing after rapid off first, opening and closing smoothly, no vibration. , rubber seal, sealed performance is good, wear resistance, long service life. Rubber cushion, opening and closing smoothly, no vibration, no noise. Than the old check pneumatic valve small resistance, has obvious energy saving effect.
